Inov-8 Road-X Lite 155 - Men’s

The Basics

Runner’s World Review

"These are minimal shoes...you get what you get," says Don Kuntzman, of Emmaus, who has run in other Inov-8 models. What you get: a low-slung and very flexible shoe geared for road racing. To keep weight down, there is no hard-rubber outsole underneath the shoe. Testers reported that this led to some slippage in wet conditions. Thick overlays form a saddle at the midfoot for a firm grasp on the foot, while the toebox opens up for a comfortable fit at the ball of the foot.

BOTTOM LINE: For most runners, this is best suited as a racing flat for dry conditions.

Runner’s World Wear Testers Say

"These are minimal shoes...you get what you get. But the sole has enough to it that when running on crushed stone I didn't feel the sharp points or edges through the sole. Also, when running on pavement the shoes offered enough cushioning to be comfortable."—Don Kuntzman, Emmaus, Pennsylvania

"The cushioning is minimal in size and weight, but sufficient and efficient, so much so that I'm going to run a marathon in the shoes."—Jim Warrenfeltz, Emmaus, Pennsylvania

We put each shoe through real-world usage and a battery of mechanical tests in our lab to provide you with objective — and exclusive — data. In addition to a shoe's weight, we measure sole thickness (everything that sits between your foot and the road), how well the foam cushions your stride, and the flexibility of the forefoot. All this is taken into account in our reviews of each shoe.
